What issues does RubyInstaller 2.4.1-1 solve?

RubyInstaller 2.4.1-1 is finally released
14 June 2017   2281

The RubyInstaller project provides a self-contained Windows-based installer that contains a Ruby language execution environment, a baseline set of required RubyGems and extensions.

Now Ruby Installer is based on MSYS2 toolchain, and the build scripts were fully rewritten. Also, the GitHub repository has changed - it is now called RubyInstaller2.


A dynamic, open source programming language with a focus on simplicity and productivity

RubyInstaller2 provides great changes in addition to newer Ruby version. Main change - DevKit is now longer available. Now RubyInstaller uses the MSYS2 for compilation of C-based gems.

The following notable changes are for the transition from RubyInstaller1 to RubyInstaller2


  • Provides ridk tool for easy MSYS2 installation/usage and system version information.
  • RubyInstaller2 bundles its own SSL/TLS CA list derived from the current Mozilla CA list into <installpath>/ssl/. See SSL-README.
  • Create a default .irbrc file for tab completition and history in irb.
  • Ability to add and use rubyinstaller-build.gem for customized Ruby-Applications. Documentation coming soon...
  • Run CI tests on AppVeyor for each git push to repository.
  • Build and deploy rubyinstaller.exe and 7z packages per AppVeyor and GitHub releases.
  • Allow MSYS2 to be shipped together with Ruby, when installed side by side or within the ruby directory. Refer to the FAQ.
  • Add an installer option to set RUBYOPT=-Eutf-8, which sets Encoding.default_external to UTF-8.


  • Built with MINGW GCC-6.3 from the MSYS2 repository.
  • Updated to Ruby-2.4.1.
  • Updated bundled libraries/DLLs.
  • RubyInstaller2 uses a separate DLL directory to avoid conflicting DLLs in the PATH.
  • RubyInstaller2 uses a DLL loading mechanism which ignores the PATH environment variable for DLL lookups, but provides a API for DLL directory-addition.
  • Use pure HTML for Ruby Core + stdlib documentation instead of CHM files.
  • Add Ruby to the PATH and have .rb + .rbw file association by default.
  • New versioning scheme: rubyinstaller-<rubyver>-<pkgrel>-<arch>.exe with pkgrel counting from 1 per rubyver.


  • No more DevKit, but integrates with MSYS2 libraries and toolchain.

RubyInstaller for Windows is a great solution for those, who would like to try Ruby but don't want to leave Windows. It helps to popularize the language and bring new coders to it.

RubyInstaller2 will be the starting pad for Ruby versions 2.4.x and upper. Ruby versions under 2.4 are based on RubyInstaller1 which is still looking for a maintainer.

Note that many big binary gems are not yet available for RubyInstaller-2.4. Try to use

gem install --platform ruby <gemname>

to enhance installation of the source gem. MSYS2 and MINGW tools are needed to be installed for this operation, for example per ridk install.

Git 2.20 to be Available

Let's check updates and features of new version control system
11 December 2018   468

Distributed version control system Git has received another update. In order for Git 2.20 to appear, 83 developers made changes 962 to the zcode. According to the team, this is an order of magnitude higher than the same figure in the largest release of the 2.x.x branch.

The git branch -l command is now a shortened version of the git branch --list - it used to help run reflog during the creation of a new branch. Developers have limited the launch of git fetch: it is only possible with an indication of --force, to avoid problems with consistency when updating the link.

The git help -a and git help -av commands to help newbies display a more verbose output. To return to the old view, just type git help - no-verbose -a. In git send-email, it is possible to extract lines with addresses that end with “-by” from signatures. This is an incompatible change, and it can be disabled by adding to the --suppress-cc = misc-by command.

  • If the repository contains files whose addresses differ only in the case of letters, a warning will be displayed during the execution of git clone.
  • The git format-patch command received the --interdiff and --range-diff options, which in a note or comment list the differences between the existing and previous versions.
  • git mailinfo learned how to recover code patches sent by email with plain text and damaged due to hyphenation.
  • git multi-pack-index now fixes damage in .midx files.
  • Creating experimental commit-graph files for large repositories takes a lot of time, so the developers have provided a form of output about the state of the process.

Performance and Development Support

  • For working builds, the -Wunused-function compilation option is provided.
  • git submodule update is completely rewritten in C.
  • One of the continuous integration (CI) tests, designed to work with the unusual/experimental/random settings, now supports midx and commit-graph files.
  • A new mechanism for finding objects among a large number of pack-files. It relies on combining all .idx files into one.

The previous version of the system was released in September 2018.
